Aprimary healthcare provider prescribes a diagnostic workup for a client who may have myasthenia gravis. what is the initial nursing goal for the client during the diagnostic phase?

The propositions are:
A. Prepare for the appearance of a myasthenic crisis
B. Maintain the present muscle strength
C. Facilitate psychologic adjustment
D. Develop a teaching plan

The right answer is B:
Myasthenia gravis is an autoimmune neuromuscular disease. It is characterized by post-synaptic involvement of the neuromuscular junction resulting in chronic fluctuating weakness of the skeletal striated musculature and excessive fatigability. This is why, until its diagnosis is confirmed, the primary goal for the nurses should be to maintain adequate activity and muscle strength to prevent muscle atrophy.
